Patent DE-3121395-A1 (DE)
Title: Process and plant for denitrification of water
Inventor: KRATZENSTEIN KLAUS ING GRAD
IPC: C02F1/64
Filed: 1981-05-29
Abstract: A process for denitrification of water is described, the nitrate contained in the water being reduced biochemically with the aid of bacteria in the presence of carbon donors. To eliminate the problems of subsequent purification to remove residues of carbon donors, a lower gaseous alkane, in particular methane, is added to the water to be treated, the water is then brought into contact with alkane-oxidising bacteria to remove the dissolved oxygen present in the water and remaining excess alkane is used as carbon donor in denitrification. The alkanes used are at the same time very cheap carbon donors. The process can be used in drinking water preparation, treatment of waste water and also in groundwater replenishment processes.

To enable several heat consumers to be supplied with heat, of which at least one is heated by high-pressure steam directly from the primary steam source and at least one other is heated by a heat carrier of low temperature, the condensate is allowed to flash in the closed receiver, during which it is held under a predetermined steam pressure and at a predetermined temperature. At least one second heat consumer is then supplied from the condensate receiver with hot water and/or steam at lower temperature.
Patent DE-3145538-A1 (DE)
Title: Process and apparatus for the treatment of metal melts with purge gas
Inventor: SINDELAR GUENTER DR ING
IPC: B22D1/00
Filed: 1981-11-17
Abstract: A process for the treatment of metal melts is carried out in a vessel by injecting purge gas in the region of the bottom of the vessel. It is to be used for removing refractory particles which, owing to their small size, rise only very slowly in the melt, if at all. To ensure that as large as possible a proportion of the refractory particles present in the melt can be removed, in order to obtain cast blocks having high quality throughout, a large region of the melt is flushed with the bubbling purge gas. The rising gas bubbles cause even very small particles which have not yet coagulated to form larger units to be carried to the surface of the melt and conveyed to the slag. Flushing of the melt is carried out in a ladle which has a high rim and is caused to tumble or tilt in different directions.

Title: Low-temperature heating process, utilising the upper calorific value of fuels
Inventor: EXSTERNBRINK KLAUS
IPC: F24H8/00
Filed: 1981-12-24
Abstract: The invention relates to a heating process for utilising the upper calorific value of fuels, in particular for a low-temperature heater, in which fuel is burned in a heating device with formation of combustion gas and the combustion gases formed initially flow upwards or sideways in the heating device, and it is characterised in that the combustion gases are passed downwards in a part of their flow path with precipitation of condensate. The precipitation of condensate takes place on surface-coated heating surfaces which have, as the coating, preferably a corrosion-resistant dense metal, for example an electrodeposited layer of chromium-nickel or the like, but especially an electrodeposited gold layer. At the outlet, the combustion gases then have a temperature of only 40 DEG C to 45 DEG C.
Patent DE-3203543-A1 (DE)
Title: Process and apparatus for producing concrete mouldings
Inventor: KRAISS RICHARD
IPC: B28B13/06
Filed: 1982-02-03
Abstract: Process and apparatus for producing concrete mouldings in a mould comprising mould core, mantle and lower sleeve, into which concrete is filled and compacted. The upper end is shaped by pressing on an upper sleeve. The lower sleeve, at least part of it, is a multi-part ring, the ring segments of which are seated movably within the ring plane on the mantle and are moved upwards together with the latter during demoulding. First of all, the mantle with lower sleeve and concrete part in it are moved up, supported from beneath, through the lower sleeve. This establishes an intermediate space between mould core and lower sleeve, into which a board can be introduced transversely on a transporting device. Then, the ring segments of the lower sleeve are moved outwards and the concrete part is set down on the board. The board can be used for a wide variety of shapes and dimensions of concrete parts. The complexity is much reduced.

Title: Electrical heating device for heated apparatuses
Inventor: THIES PETER DIPL ING
IPC: H05B3/48
Filed: 1982-03-11
Abstract: An electrical heating device for heated apparatuses, having a plurality of small heating plates which, in the operating region, have a temperature/resistance characteristic running essentially parallel to the resistance axis. The small heating plates are placed with their contacting surfaces at the top and bottom on power supply leads which are designed as sheet-metal strips, and are inserted into a moisture-proof, heating-temperature-resistance insulating material sheath, from which only the connecting conductors are passed out. The small heating plates are arranged in an insulating material strip or in holes or recesses, corresponding to the shape of the small heating plates, in the insulating material strip and overhang the insulating material strip with their contacting surfaces. The sheet-metal strips are pressed against the small heating plates, with pretensioning, by the insulating material sheath. Located between the sheet-metal strips and the contacting surfaces of the small heating plates are flexible conductor elements, as a result of which the contact resistance between the contacting surfaces and the sheet-metal strips is reduced. <IMAGE>
Patent DE-3211761-A1 (DE)
Inventor: SCHWABE ULRICH DR PHIL
IPC: H01L21/285
Filed: 1982-03-30
Abstract: A method for the manufacture of integrated MOS-field effect transistor circuits in silicon gate technology and wherein diffusion source and drain zones are coated with a high melting point silicide as low-impedance printed conductors. The diffusion zones and polysilicon gates are made low-impedance through selective deposition of the metal silicide onto surfaces thereof. The selective deposition, which proceeds by use of a reaction gas eliminating hydrogen halide, simplifies the process sequence and is fully compatible with conventional silicon gate processes. Because of the high temperature stability, preferably tantalum silicide is employed. The invention is useful in the manufacture of MOS-circuits in VLSI-technology.
Patent DE-3212009-A1 (DE)
Inventor: KREFT WILFRIED ING GRAD
IPC: C04B7/44
Filed: 1982-03-31
Abstract: Fine-grained material such as raw cement meal is preheated in a multi-stage cyclone preheater, precalcined in a precalcination zone, sintered in a rotary kiln, and cooled in a cooler. Exhaust gases from the kiln are delivered to the precalcining zone and then to the preheater. Tertiary air from the cooler is divided into two streams one of which is mixed with kiln exhaust gases between the kiln and the precalciner and the other of which is delivered directly to the precalciner. The quantity of tertiary air flowing through each branch is regulated to maintain the temperature of the kiln exhaust gases at a selected value.
Patent DE-3213335-A1 (DE)
Title: Method for recognising different dielectric materials
Inventor: KURANDT FRITZ
IPC: G01N22/00
Filed: 1982-04-07
Abstract: For the purpose of recognising different dielectric materials of a test object by means of microwaves, microwave energy of a fixed frequency, which has been launched at a suitable location into a cavity resonator used for the measurement, or which has been generated therein, is extracted from the resonator at the front end thereof by means of a diaphragm, a detector located in the resonator being set to a sensitive operating point by means of external bias. This detector, by means of destructive interference which is generated with the aid of the power generated in the resonator or launched thereinto and reflected by the diaphragm, is set to a low output which, however, is sufficient for effective matching of the detector to the resonator. By positioning the dielectric test object in front of the diaphragm orifice outside the resonator in the short-range field region of the coupling orifice, said destructive interference is cancelled to a greater or lesser extent, as a result of which the rectified voltage on the detector diode is shifted to more negative values. This shift is recognised as a signal which is characteristic of the test object. <IMAGE>
